IMPROVEMENT IN THlLL-COUPLINGS FOR SLEIGHS.

Specification forming part of Letters Patent No. 163,781, dated May 25,1875 application tiled April 8, 1875.

To all whom it may concern:

Be it known that I, C. H. JOHNSON, of Southington, in the county ofHartford and in the State of Connecticut, have invented certain new anduseful Improvements in Slegh-Shackles; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing making a part of thisspecification, in which my improved device is shown in perspective.

The design of my invention is to lessen the cost of shackle-irons usedfor connecting the shafts of a sleigh to or with the cross-bar, and itconsists in the employment of a shank or bolt for connecting theshackle-eye to or with the cross-bar, substantially as and for thepurpose hereinafter specified.

In the annexed drawing, A represents the eye of my improved shackle,which is constructed in the usual manner, and ha-s pivoted thereto ashaft-iron, B, having any ordinary form. From the rear side or end oftheshackleeye A extends horizontally rearward a shank, A', that has,preferably, the form of an ordinary square-shank carriage-bolt, and isthreaded at its end, so as to enable it to receive a nut, a. To connectthe shackle-eye to or with the cross-bar of a sleigh, an opening havinga sufficient size to receive the bolt A is formed in said bar, said boltinserted within said opening, and the nut a placed upon its end andscrewed home.

As constructed, the shackle costs materially less than those ordinarilyused, while for the `purpose intended it has all necessary strength,
